The whole interface ref. counting depends on that as well as e.g. the
"as" operator.

My opinion about the for-in loop:
- I won't implement it
- if somebody else implements it in a delphi compatible manner: fine
- if somebody else implements it in a delphi compatible manner solving
the flaws: great
- if somebody else has ideas how the existing classes can be extended
without drawbacks by more sophisticated iterators, go ahead, this won't
interfere with Paul's stuff
